A lot of engineering involves iteration. In this video I iterate through several turbine designs, searching for the most efficient conversion of the water jet to mechanical power. The logic that a smaller diameter will spin the generator faster, quickly runs up against the total power available and efficiency of the turbine itself. Lesson learned: power generation is not as simple as we’d like to think!

Pelton simulation depicted in video:

Summary:
In part 1 I connected an off-the-shelf DC generator to a pelton wheel and drove it with runoff from a large section of my roof. Though I calculated 2 watts of available power and planned on only collecting 50% of it, the actual output was only .19 watts.
In part 2 I design and build a permanent magnet alternator then rectify the AC into DC power to enhance the efficiency.
In part 3 I iterate nozzle and turbine designs to see if we can get a full watt of power.
